I have Windows 7 on 64 bit. I was using GridMove fine until I bought a large LCD, and I had to use a custom DPI to increase font in the system.That time GridMove started to act weird, does not respect anymore the display size, and rules I set. I set to use a custom DPI size of 115%. Please look into and correct.

I'd suggest finding the original GridMove thread and posting there. You'll also need to provide more details as to what you did. You'll almost certainly get better support in that thread than by posting a new one. Not to mention that this thread may be moved, as it is not a new request, rather a comment on an existing one.

So you came along and found Java(insert programming language here)? Randomly? Well then, you're just like me! Java fiends rule. (Though other languages do have their uses.)
